ROLLER EMPLOYED IN TEXTILE MACHINES.

Application filed December 20, 1923, Serial No. 681,760. Renewed June 11, 1925.

To ZZ "ILIZOWL it may concern:

Be it known that 1, James LEVER Rnsi-r- TON, a subject of the King of Great Britain, of Kay Street, Bolton, in the county of Lancaster, England, machine maker, have invented new and useful Improvements in Rollers Employed in Textile Machines, of

which the following is a specification.

The invention relates to improvements in or relating to rollers for textile machines In certain textile machines rollers weighted at their ends by means of suspended weights are employed and it is found in practice that these weights in course of time cause the rollers to bend thus throwing them out of alignment and especially is this the case with the detaching rollers of combing machines.

Now the object of the present invention is to construct a roller of the type indicated in such manner that the defect above pointed out will be remedied.

For this purpose the roller is constructed with a core having a taper or curvature adjacent its ends but is provided with cylindrical journals as heretofore and said core is preferably of smaller diameter than that desired for the finished roller and the centre part of said core is preferably cylindrical as heretofore and this core is encased with a shell or casing having a cylindrical bore.

The casing is adapted to fit tightly upon the roller and if desired be fixed therewith y any suitable means such for example as screws, pegs or the like or a key and the arrangement is such that on account of the taper of the core a slight space is left between the bore of the shell, or casing and the tapered part of the core so that a certain amount of play is provided between the parts at their ends.

The effect of this is that the weights have a tendency to bend the core while the shell and therefore the periphery of the roller remains in alignment, thus overcoming the defect above pointed out in rollers of this class.

The shell or casing may be formed of any suitable metal or material and may be cast .or otherwise formed and may be covered with leather or other suitable material as may be desired.

And in order that the said invention may he more clearly understood and readily carried into effect I will proceed aided by the accompanying drawings more fully to describe the same.

Description of the drawings.

Figure 1 is a sectional elevation of a detaching roller of a combing machine constructed according to the present invention, and

Figure 2 is a similar view to Figure 1 illustrating a modification thereof.

Referring to Figure 1, 1 represents a core or spindle preferably of steel provided with the usual cylindrical journals 2 and said spindle l is of cylindrical formation for a short length at the centre thereof as shown at 1 and is tapered at either end from the cylindrical portion 1 down to a lesser diameter adjacent the journals 2, as shown at 1 and 1.

3 represents a casing consisting of a metal tube preferably a weldlcss steel tube having a constant bore, that is to say a bore of cylindrical formation and said casing 3 is adapted to fit tightly upon the cylindrical portion 1 of the spindle 1, and is fixed thereon by any suitable means such as keys, screws, pegs or the like (not shown) the arrangement being such that a slight space is left between the spindle 1 and said casing 3, adjacent the ends thereof as shown, thus the whole of the weight acts at the centre of the spindle 1 and is equally distributed througle out the casing 3, thereby avoiding excessive or uneven wear of the leather covering of the roller and maintaining a constant grip upon the cotton throughout the length of the roller in consequence of the resistance to deflection offered by the spindle 1.

In Figure 2 is illustrated a modification of the device in which the spindle 4 is provided with two cylindrical bearing portions at (the length of spindle between the same being of reduced diameter in order to avoid contact with the casing 3 which is identical with that shown in Fig. 1) and tapered por tions 4 and 4 similar to those hereinbefore described with regard to Figure 1. This construction would be specially suitable in. machines in which very long rollers are cinploycd.

lVhat I claim as my invention and desire to secure by Letters Patent is 1. A roller for textile machines, compris in a steel spindle of cylindrical formation approximately at the centre thereof, and

tapered at each end, a casing of Weldless steel tube 01" censtant bore, said casing lit ting tightly upon said cylindrical portion of the spindle, so that a tapered space exists be- 4 tween the tapered part of the spindle and the cylindrical casing substantially as here- 111 set-forth.

2. In a roller for textile inachlnes as claimed in claim 1, :1- inodified spindle l121V- ing two cylindrical bearing portions, and having a reduced diameter between said two bearing portions and tapering towards each end, substantially as herein set forth.

In testimony whereof I have signed my name to this specification.
